31 CALDER AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 31 CALDER AVENUE sales between March 1995 and December 2019 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the May 1997 sale was for 42% above the HPI. So the extrapolation line tracks at 42% above the HPI over time, until the December 2019 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.
